                                            NEWSLETTER                                 2^nd  Quarter 2014

Dear Shareholders:

The numbers are in for the second quarter of 2014, and Hartman Short Term Income Properties XX, Inc. (the “Company”) continues to perform strong.  The fund generated revenue totaling approximately $2.8 million and funds from operations (“FFO”) Yield¹ of 4.4% for the quarter.  Please see the chart below for the relevant individual property and fund performance:

As the Texas real estate markets continue to surpass pre-recession highs in overall occupancy and absorption, as well as historical lows in vacancy, now is an excellent time to be a shareholder. There are a number of activities taking place that we are thrilled to report on to our shareholders.

We are excited to announce that on March 11^th, we closed on Gulf Plaza, a fully occupied six-story, extensively renovated Class B+ office building containing approximately 126,651 square feet located in the booming Energy Corridor office submarket in Houston, Texas.

¹FFO Yield: Funds from operation yield – Net Operating Income less interest expense divided by current equity investment in property.

Gulf Plaza is the 5^th acquisition, and we believe it is an excellent addition, as it is currently producing an FFO Yield of approximately 7.1%.

On June 13, 2014, the Company closed on the Mitchelldale Business Park (Mitchelldale), a 377,752 square foot, twelve (12) building industrial park. Mitchelldale is located in the Northwest Industrial Submarket, Houston’s largest industrial submarket, making up over a quarter of all industrial space in Houston. The property is expected to produce a first year FFO Yield of approximately 10.84% and grow to 12.61% in year five, both of which are significantly accretive to the overall fund.

On July 2, 2014, the Company executed a Purchase and Sales agreement for two Class B office buildings situated in the heart of San Antonio’s thriving North Central office submarket. The 180,000+ square foot property is located just minutes from San Antonio International Airport. The property is well occupied and has a heavy concentration of oil and gas tenants. Based on the existing CMBS loan to be assumed and the in place income, we project an 11% initial FFO.

As we continue to strive for higher occupancy using an aggressive approach to leasing, our efforts are being rewarded. A leading indicator of our progress is increased occupancy. The summary below details our leases, expansions and renewals executed in the second quarter.

In order to capitalize on the historically low interest rates the Company worked with ING, an Atlanta based Life Company, to refinance Richardson Heights, Cooper Street, and Bent Tree Green properties and to provide acquisition debt for Mitchelldale. We have secured an annual rate of 4.61% for approximately $50 million long-term debt for 10 years. The loan closed on June 13, 2014.  Additionally, the Company has added Gulf Plaza to our existing line of credit with Texas Capital Bank with a $7 million borrowing base value.

Based on our budget and leasing activity, we expect to increase our fund FFO Yield to 8.3% by the February of 2015. Below is a twenty-six month graphical representation of the fund’s six properties including, FFO Yield and occupancy for 2014. As you can see the fund FFO gets to 8.3% by the end of the year, when including new acquisitions and signed leases.
